A New Backpressure Algorithm for Joint Rate Control and Routing with Vanishing Utility Optimality Gaps and Finite Queue Lengths | The backpressure algorithm has been widely used as a distributed solution to
the problem of joint rate control and routing in multi-hop data networks. By
controlling a parameter $V$ in the algorithm, the backpressure algorithm can
achieve an arbitrarily small utility optimality gap. However, this in turn
brings in a ... | 1 | 0 | 1 | 0 | 0 | 0 |
Lifshitz transition from valence fluctuations in YbAl3 | In Kondo lattice systems with mixed valence, such as YbAl3, interactions
between localized electrons in a partially filled f shell and delocalized
conduction electrons can lead to fluctuations between two different valence
configurations with changing temperature or pressure. The impact of this change
on the momentum... | 0 | 1 | 0 | 0 | 0 | 0 |
Diversity from the Topology of Citation Networks | We study transitivity in directed acyclic graphs and its usefulness in
capturing nodes that act as bridges between more densely interconnected parts
in such type of network. In transitively reduced citation networks degree
centrality could be used as a measure of interdisciplinarity or diversity. We
study the measure... | 1 | 0 | 0 | 0 | 0 | 0 |
Superluminal transmission of phase modulation information by a long macroscopic pulse propagating through interstellar space | A method of transmitting information in interstellar space at superluminal,
or $> c$, speeds is proposed. The information is encoded as phase modulation of
an electromagnetic wave of constant intensity, i.e. fluctuations in the rate of
energy transport plays no role in the communication, and no energy is

Causal Regularization | In application domains such as healthcare, we want accurate predictive models
that are also causally interpretable. In pursuit of such models, we propose a
causal regularizer to steer predictive models towards causally-interpretable
solutions and theoretically study its properties. In a large-scale analysis of
Electr... | 1 | 0 | 0 | 1 | 0 | 0 |
Voice Disorder Detection Using Long Short Term Memory (LSTM) Model | Automated detection of voice disorders with computational methods is a recent

Topology of two-dimensional turbulent flows of dust and gas | We perform direct numerical simulations (DNS) of passive heavy inertial
particles (dust) in homogeneous and isotropic two-dimensional turbulent flows
(gas) for a range of Stokes number, ${\rm St} < 1$, using both Lagrangian and
Eulerian approach (with a shock-capturing scheme). We find that: The

Trimming the Independent Fat: Sufficient Statistics, Mutual Information, and Predictability from Effective Channel States | One of the most fundamental questions one can ask about a pair of random
variables X and Y is the value of their mutual information. Unfortunately, this
task is often stymied by the extremely large dimension of the variables. We
might hope to replace each variable by a lower-dimensional representation that
preserves ... | 1 | 1 | 0 | 1 | 0 | 0 |
Statistical Physics of the Symmetric Group | Ordered chains (such as chains of amino acids) are ubiquitous in biological

systems whose sta... | 0 | 1 | 0 | 0 | 0 | 0 |
A New Phosphorus Allotrope with Direct Band Gap and High Mobility | Based on ab initio evolutionary crystal structure search computation, we

An open shop approach in approximating optimal data transmission duration in WDM networks | In the past decade Optical WDM Networks (Wavelength Division Multiplexing)

Optimal prediction in the linearly transformed spiked model | We consider the linearly transformed spiked model, where observations $Y_i$
are noisy linear transforms of unobserved signals of interest $X_i$:
\begin{align*}
Y_i = A_i X_i + \varepsilon_i, \end{align*} for $i=1,\ldots,n$. The transform

Self-Normalizing Neural Networks | Deep Learning has revolutionized vision via convolutional neural networks

However, success stories of Deep Learning with standard feed-forward neural
networks (FNNs) are rare. FNNs that perform well are typically shallow and,
therefore canno... | 1 | 0 | 0 | 1 | 0 | 0 |
Real-time Fault Localization in Power Grids With Convolutional Neural Networks | Diverse fault types, fast re-closures and complicated transient states after

Effective identifiability criteria for tensors and polynomials | A tensor $T$, in a given tensor space, is said to be $h$-identifiable if it
admits a unique decomposition as a sum of $h$ rank one tensors. A criterion for
$h$-identifiability is called effective if it is satisfied in a dense, open
subset of the set of rank $h$ tensors. In this paper we give effective

Functoriality properties of the dual group | Let $G$ be a connected reductive group. In a previous paper,
arXiv:1702.08264, is was shown that the dual group $G^\vee_X$ attached to a

Langlands dual group $G^\vee$ of $G$. Here, we prove that the dual group is

Chaotic dynamics around cometary nuclei | We apply a generalized Kepler map theory to describe the qualitative chaotic

Riemannian curvature measures | A famous theorem of Weyl states that if $M$ is a compact submanifold of

An infinite class of unsaturated rooted trees corresponding to designable RNA secondary structures | An RNA secondary structure is designable if there is an RNA sequence which
